Graph Arrangement with For Loops

[#1]

I want to understand how to arrange graphs.
When a user wants to arrange them in two rows with three graphs in each row, I can achieve that using the script below:

New Window( "Test", 
	
	
	H List Box(
		For( i = 1, i < 4, i++,
			Graph Builder(
				Size( 528, 450 ),
				Show Control Panel( 0 ),
				Variables( X( :age ), Y( :height ) ),
				Elements( Points( X, Y, Legend( 3 ) ), Smoother( X, Y, Legend( 4 ) ) )
			)
		),

	),
	H List Box(
		For( i = 1, i < 4, i++,
			Graph Builder(
				Size( 528, 450 ),
				Show Control Panel( 0 ),
				Variables( X( :age ), Y( :height ) ),
				Elements( Points( X, Y, Legend( 3 ) ), Smoother( X, Y, Legend( 4 ) ) )
			)
		),

	)
	
);

However, when I use a for loop, I am unable to achieve the same effect, as shown below:

New Window( "Test", 
	
	For( k = 1, k < 3, k++,
		H List Box(
			For( i = 1, i < 4, i++,
				Graph Builder(
					Size( 528, 450 ),
					Show Control Panel( 0 ),
					Variables( X( :age ), Y( :height ) ),
					Elements( Points( X, Y, Legend( 3 ) ), Smoother( X, Y, Legend( 4 ) ) )
				)
			)
		)
	)
);

What should I modify to make the output of the for loop display the graphs correctly?

I suggest you use Lineup Box(N Col(3)) instead of H List Boxes

Edit:

Here is simple example

Names Default To Here(1); 

dt = open("$SAMPLE_DATA/Big Class.jmp");

lub = Lineup Box(N Col(3));
For(i = 1, i <= 10, i++,
	lub << Append(
		dt << Graph Builder(
			Show Control Panel(0),
			Variables(X(:weight), Y(:height), Overlay(:sex)),
			Elements(Points(X, Y, Legend(9)), Line Of Fit(X, Y, Legend(11)))
		);
	)
);

nw = New Window("report",
	lub
);
